How did the lab activities help you answer the lesson question, "How are minerals and rocks classified?” What did you learn from conducting this lab?

Lab activities support to investigate the composition and characteristics of every tiny scrap and give a comprehensive explanation about that.

Explanation:

For example, the andesite of Mars includes quartz, feldspar,

amphibole, and different metals. Rocks are grouped into Volcanic rocks, Metamorphic rocks, Sedimentary rocks.

the metal quartz is made of two parts, silicon and

oxygen. Other minerals may include various elements. For

instance, the crystal amphibole is made up of a ironing list of

elements including Na, Ca, Mg, Fe,

aluminum, silicon, and oxygen.

In the lab, I conducted tests and observed the physical properties of minerals. I combined my observations to identify the mineral samples based on their hardness, streak, color, and luster, and on how they break. I also identified rock samples based on their physical properties, such as grain size and foliation. I learned that the properties that are used to classify or group minerals and rocks can also be used to identify them. I also learned that the physical properties of rocks can tell us how they were formed.

explination: i took the test

answer: the answer is b

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
